GPA vs Cumulative GPA: What’s the Difference?
GPA and cumulative GPA are closely related—but they’re not the same.
- GPA usually refers to your grade point average for one term, like a semester or quarter.
- Cumulative GPA is your overall GPA across multiple terms, showing your academic performance over time.
Why It Matters
Colleges and scholarship boards often focus more on your cumulative GPA because it reflects your long-term consistency—not just one good (or bad) semester.
Key Difference Table
| Term | What It Includes | When It’s Used |
|---|---|---|
| GPA | Single semester or grading period | Mid-year reports, academic probation, course planning |
| Cumulative GPA | All completed courses to date | College applications, honors programs, final transcripts |
How to Calculate Cumulative GPA (Step-by-Step)
To calculate your cumulative GPA, follow this formula:
Cumulative GPA = (Total Grade Points for All Semesters) ÷ (Total Credit Hours Attempted)
Example: 2-Semester Cumulative GPA
Let’s say you took the following courses:
Semester 1
| Course | Grade | Credits | Grade Points |
|---|---|---|---|
| English | A (4.0) | 3 | 12.0 |
| Math | B+ (3.3) | 4 | 13.2 |
| History | B (3.0) | 3 | 9.0 |
Semester 1 GPA = (12.0 + 13.2 + 9.0) ÷ 10 credits = 3.42
Semester 2
| Course | Grade | Credits | Grade Points |
|---|---|---|---|
| Biology | A- (3.7) | 4 | 14.8 |
| Chemistry | B (3.0) | 3 | 9.0 |
| PE | A (4.0) | 1 | 4.0 |
Semester 2 GPA = (14.8 + 9.0 + 4.0) ÷ 8 credits = 3.45
Final Cumulative GPA
- Total Grade Points = 12.0 + 13.2 + 9.0 + 14.8 + 9.0 + 4.0 = 62.0
- Total Credits = 10 + 8 = 18
- Cumulative GPA = 62.0 ÷ 18 = 3.44
✅ Your Cumulative GPA after 2 semesters is 3.44

How to Calculate GPA: Step-by-Step Guide
Calculating your GPA might seem tricky at first, but it’s pretty straightforward when broken down into steps. Whether you’re working with an unweighted or weighted GPA, here’s how to do it:
1. Assign Grade Points to Each Class
Each letter grade corresponds to a specific number of grade points. Here’s the standard unweighted scale:
- A = 4.0
- B = 3.0
- C = 2.0
- D = 1.0
- F = 0.0
For a weighted GPA, advanced courses like AP or honors may add extra points:
- A in AP/Honors = 5.0 (instead of 4.0)
- B in AP/Honors = 4.0 (instead of 3.0)
2. Multiply Grade Points by Credit Hours
Some classes, like core subjects, may carry more credit hours. Multiply the grade points by the number of credits for each class. For example:
- An A (4.0) in a 3-credit class = 4.0 × 3 = 12 points
- A B (3.0) in a 2-credit class = 3.0 × 2 = 6 points
3. Add Up Total Grade Points
Add the grade points from all your classes. For instance:
- Class 1: 12 points
- Class 2: 6 points
- Class 3: 8 points
- Total: 26 points
4. Divide by Total Credit Hours
Finally, divide the total grade points by the total credit hours to get your GPA. If your total grade points are 26 and total credits are 7:
- GPA = 26 ÷ 7 = 3.71
How Grades Like A+ or A- Affect GPA
Letter grades like A+ and A- can fine-tune your GPA. Here’s how they typically work:
- A+ = 4.3 (on some scales)
- A- = 3.7
- B+ = 3.3
- B- = 2.7
For example, if you earn an A- in a 3-credit class:
- Grade Points = 3.7 × 3 = 11.1
Small differences like these can add up, especially when calculating GPAs over several semesters or in competitive environments like college admissions.

GPA Scales & Conversion Charts
Understanding how GPA is calculated starts with knowing the grading scale your school uses. While many U.S. high schools and colleges use a 4.0 scale, some apply weighted systems or percentage-based scales. Here’s how they compare:
Standard 4.0 Scale (Unweighted)
| Letter Grade | Percent Range | GPA Value |
|---|---|---|
| A | 90–100% | 4.0 |
| B | 80–89% | 3.0 |
| C | 70–79% | 2.0 |
| D | 60–69% | 1.0 |
| F | Below 60% | 0.0 |
This is the most common grading scale used in unweighted GPA calculations.
Weighted 5.0 Scale (for Honors, AP, or IB Classes)
Some schools add extra points to more challenging courses:
| Letter Grade | Regular Class | Honors | AP/IB |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
Tip: Always check your school’s course catalog or counselor guide — not all schools use the same weighting system.
100-Point Scale (Percentage-Based)
Some schools use a percentage system, especially in progress reports or transcripts. To convert a percentage to GPA:
| Percent Range | GPA Equivalent |
|---|---|
| 90–100% | 4.0 |
| 80–89% | 3.0 |
| 70–79% | 2.0 |
| 60–69% | 1.0 |
| Below 60% | 0.0 |
Many colleges will convert these scores to a 4.0 scale when reviewing applications.
When GPA Types Matter Most
Different GPA types—weighted, unweighted, and cumulative—can affect your academic future in different ways:
College Admissions
- Colleges usually recalculate your GPA using their own scale, often ignoring weighting or retaking policies.
- Some competitive schools consider both weighted GPA (to reward rigor) and unweighted GPA (to compare across applicants).
Scholarships
- Merit-based programs often list a minimum unweighted GPA (e.g., 3.5 or higher).
- Honors/AP weighting may help you stand out in competitive pools.
Transcripts & Class Rank
- Cumulative GPA is shown on your transcript and is used to determine class rank, honors graduation, or eligibility for programs like NHS.
✅ Pro tip: Always know what kind of GPA a college, scholarship, or program is asking for—they don’t all want the same thing.

Weighted vs. Unweighted GPA: What’s the Difference?
Not all GPAs are created equal. Most high schools calculate two types: unweighted GPA and weighted GPA. Here’s what you need to know—and how colleges view both.
🔹 What Is an Unweighted GPA?
An unweighted GPA is based on a 4.0 scale where all classes are treated equally—whether it’s AP Calculus or standard Algebra I.
| Letter Grade | Unweighted GPA (4.0 scale) |
|---|---|
| A | 4.0 |
| B | 3.0 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
✅ Best for: A quick snapshot of how well you’re doing overall—without factoring in course difficulty.
🔸 What Is a Weighted GPA?
A weighted GPA gives extra points for harder classes, like AP, IB, or honors courses. It’s usually based on a 5.0 scale, rewarding academic challenge.
| Letter Grade | Standard Class | Honors Class | AP/IB Class |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |
| F | 0.0 | 0.0 | 0.0 |
Pro tip: If your school offers weighted classes, it can help your GPA exceed 4.0—which looks great on competitive college applications. Try it out using our free GPA calculator tool to compare your weighted and unweighted GPA.

⚖️ Weighted vs. Unweighted GPA: Side-by-Side
| Aspect | Unweighted GPA | Weighted GPA |
|---|---|---|
| Scale | 0.0 to 4.0 | 0.0 to 5.0 (varies by school) |
| Class difficulty | Not factored in | Extra credit for AP, IB, Honors |
| Fairness | Equal across all students | Rewards advanced coursework |
| Max GPA possible | 4.0 | Often 4.5–5.0 |
| Used by colleges | Many recalculate to 4.0 | Still reviewed to assess rigor |
Do Colleges Prefer Weighted or Unweighted GPA?
Both matter.
- Colleges recalculate your GPA using their own formulas—often based on your cumulative GPA—but they also consider the rigor of your course load.
- Some top universities (like UC schools) cap the weighted GPA at 8 semesters of honors/AP classes.
- Your high school profile (sent with your transcript) helps colleges interpret your GPA in context.
Check Your School’s Policy
Weighting systems aren’t universal. Some schools use:
- 4.0, 4.5, or 5.0 scales
- Caps on how many classes are weighted
- Different weights for AP vs IB vs dual enrollment
Tip: Ask your guidance counselor or review your school’s course catalog to confirm how GPA is calculated. If you’re planning summer coursework or AP classes, check out our summer prep for high school students guide to help you plan strategically.

The Impact of GPA on Your Academic and Career Goals
Your GPA is more than just a number—it’s a critical tool that shapes your future in academics and beyond. Whether you’re a high school student eyeing top colleges or a college student aiming for career opportunities, GPA plays a major role in opening doors.
Why GPA Matters
- Academic Standing: Your GPA reflects your overall performance in school. A strong GPA can earn you a spot on the honor roll or keep you eligible for competitive programs.
- Scholarships: Many scholarships use GPA as a key factor to decide who gets awarded. For example, a merit-based scholarship might require a minimum GPA of 3.5.
- Honors Societies: Prestigious groups like the National Honor Society often require a high GPA for membership, boosting your resume and academic credibility.
- Career Opportunities: Some employers and internship programs consider GPA when screening applicants, as it indicates discipline, time management, and consistency.
For instance, if you’re applying for a scholarship, a 4.0 GPA might automatically put you on the shortlist. Similarly, companies hiring interns often give preference to students with strong academic records.
In some cases, students may have the option to take a pass/fail grading system, which can impact their GPA in different ways.
How Colleges Use GPA in Admissions
Colleges evaluate GPA alongside other factors like extracurriculars and test scores to gauge a student’s potential. The chart below highlights the weight of each component in the admissions process.

Colleges see GPA as a reflection of your dedication and ability to handle academic challenges. However, they don’t look at GPA in isolation. It’s often evaluated alongside your extracurricular activities, recommendation letters, and test scores like the SAT or ACT.
For example:
- A student with a slightly lower GPA but outstanding extracurricular achievements might still stand out to admissions officers.
- Conversely, a perfect GPA can strengthen your case if other areas, like test scores, are average.
Admissions officers also consider the context of your GPA. Did you take challenging AP or IB courses? Did your GPA improve significantly over time? These factors can showcase your growth and resilience.
